only way to know for certain is by measuring the clearance. Theres more to the problem than just lift, duration & overall valve timing are as much a factor. you could have 2 cams with same lift, but differant valve timing, 1 would work & the other may not. & of course it has to do with what pistons are in it, what head gasket, have the decks been milled, or the heads shaved..all these are an issue.
